摘要：

Reaction of [(Mn8Mn4O12)-Mn-III-O-IV(CH3COO)(16)(H2O)(4)] with [A-alpha-PW9O34](9-) in a 1:2 molar ratio in aqueous, acidic medium resulted in the manganese(III)-containing, sandwich-type tungstophosphate [Mn-3(III)(H-2-O)(5)(A-alpha-PW9O34)(2)](9-) (1). Polyanion 1 crystallizes as a mixed potassium/cesium/guanidinium salt in the triclinic space group P (1) over bar, with cell parameters a = 13.1718(19) angstrom, b = 16.505(2) angstrom, c = 22.842(4) angstrom, alpha = 104.141(7)degrees, beta = 106.267(8)degrees, gamma = 101.369(6)degrees, V = 4430.6(12) angstrom(3), and Z = 2. The title polyanion comprises two [A-alpha-PW9O34](9-) Keggin fragments linked via three Mn-III ions, two of which are 6-coordinated and one is 5-coordinated. Polyanion 1 was further characterized by IR, TGA, elemental analysis, magnetic measurements, and electrochemistry. (C) 2012 Elsevier Ltd. All rights reserved.
